I PAINT MIXER.

Application filed October 4:, 1924. Serial No. 741,570.

This invention relates to improvements in devices for mixing liquids of all kinds,

of open or. closed vessels; one which may be readily raised and lowered, and hence adjusted, to suit mixing vessels of varying depths; and one which may be swung laterally and out of the plane of operations when not in use after the mixing operations have been completed, so as not to interfere with any necessary manipulation of the mixing vessel or of the liquid therein. At the same time, when the mixer is in operation, it may be rigidly held against lateral and vertical movements.

A further object of the invention is to produce a simple and inexpensive device, and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of ref erence indicate corresponding parts in the several views:

Figure 1 is a side elevation of the mixer, in its raised position.

Figure 2 is a fragmentary perspective view showing an adjustable extension mixing member applied to the fixed mixing member.

Referring now to the numerals of reference on the drawings, 1 and 2 denote upper and lower brackets, spaced apart a considerable distance, and rigidly secured to a wall 3 by any suitable means. Supported by and extending between these brackets is a circular post 1, on which is turnably mounted the vertically spaced hoses 5 disposed at the upper and lower ends of a rigid frame 6 of suitable design.

Mounted on the frame on top thereof is an electric motor 7 having a bevel pinion 8 on its shaft engaging a bevel gear 9. This gear is fixed on a vertical shaft 10 which is turnably mounted in a bearing sleeve eleven provided with the frame 6 at the thereof. opposite the bosses in Removably fixed on the lower end of the shaft 10, below the sleeve 11, is a head 12, in which are permanently secured in any suitable means, the upper ends of a substantially U-shaped mixing device 13, preferably formed of stout wire, the legs of which depend vertically from the head, to a point considerably below the lower end of the frame.

To maintain the frame 6 at any predetermined level relatve to the post 4, I mount a vertically adjustable collar 14 on the latter, against which the under face of the lower boss 5 bears. I

To prevent undesired rotation of the frame, I provide a brace rod structure extending from the frame 6 adjacent its outer end to the wall 3 at a suitable horizontal angle to the frame. This structure comprises a tubular. member 15 swivelly mounted onto the wall as by means of an eye bolt 16 positioned at a suitable height, and a rod 17 slidably mounted in the member 15 from the free end. thereof. The outer end of the rod 17 carries a hook 18 flexibly and removably fitted in an eye 19 formed with the frame 6 at a suitable point, preferably adjacent the outer and upper end thereof. j

The brace structure is therefore automatically adjustable as to length, so that the frame 6 may be maintained at the same angle" to the wall irrespective of its height relative to the floor on which the mixing vessel is supported.

A thumb screw or clamp 20 is mounted in member 15 to bear against the rod17, so as to hold saidmembers against telescoping movement when desired. To hold the frame at its uppermost position on the post 4 when not in use, I provide a fixed dishshaped catch member 21 on the upper bracket 1, extending thereabout concentric with the post. This catch, when the frame is moved to its uppermost position, is automatically engaged by a pawl 22 mounted 011 the frame 6, said pawl being normally held in engagement with the catch by a spring 23, and being releasable therefrom at will by pressing down on a finger pad 24. formed with the pawl.

3;; masen of this; esnstructionths frame may be held clear of a mixing vessel without having to move up the collar 14 every time, which may thus be left in a predetermined fixed position. Also, the frame may be swung to the wall whenever desired without the holding catch means being disconnected. In this case the brace structure is disconnected from the frame and allowed to hang down alongside the wall.

In the event that mixing operations are being carried out in a vessel of a greater depth than that for which the mixing member 13 is intended, I may apply an extension member to the latter. This extension comprises a flexible U-shaped member symmetrical to the member 13 and having its inner face concavedto slidably fit over the legs of the member 18 from the outside thereof, as: shown in Figure 2. lVhile such a member ,could be made in various ways, I

contemplate using a piece of pipe or tubing having an internal diameter about the same as that of the wire 13, and cutting the same in two lengthwise'before bending it to the desired U-shaped form. Hooks 26 engage the member 25 on opposite sides thereof above the lower end of member 13, said hooks having straight portions 27 extending 'towards each other and being threaded on PlugsBO projecting radially from the sleeve.

The unit 13 being removable from the shaft, it may be interchanged with others of different lengths without necessarily using the extension device.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfillsthe objects of the invention as set forth herein.

IVhile this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such'detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

, Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. In a mixing device, a vertical post, a frame for carrying a mixing element mounted on said post for free turning and sliding movement, and detachable brace means normally preventing turning movement of the frame.

2. In a mixing device, a vertical post adapted to be secured against a'wall, a frame for carrying a'mixing element mounted on the post for free turning and sliding movement, brace means fixed at one end on the wall at a certain height to one side of the frame, and extending thence to a connection with the frame, and means incorporatce with the brace means whereby the latter may function irrespective of the vertical setting of the frame, and the frame may be maintained at the same angle to the wall with any such setting.

3. In a mixing device, a vertical post, a frame for carrying a mixing element mounted on said post for free turning and sliding movement, and brace means for preventing turning movement of the frame irrespective of the vertical position of the frame on the post.

4. In a mixing device, a vertical post adapted to be secured against a wall, a frame for carrying a mixing element mounted on the post for free turning and sliding movement, telescopic brace means extending from'the frame to the wall to one side of the post, and clamp means holding the brace means at any telescopic setting.

5. In a paint mixing device, a fixed vertical post, a frame for carrying a mixing element mounted on the post for free sliding movement thereon, and adjustable means limiting the travel of the frame on the post.

6. In a paint mixing device, a fixed vertical post, a frame for carrying a mixing element mounted on the post for free sliding movement thereon, a'ndreleasable catch means between the post and frame for automatically holding the latter against downward movement when raised to its limit of upward movement,

7. In a paint maxing device, a fixed vertical post, a frame for carrying a mixing element mounted on the post for free sliding and turning movement, and releasable catch means between the post and frame for automatically holding the latter against downward movement when raised to its limit of upward movement, and functioning irrespective of the horizontal position of the frame on the post.

8. In a paint mixing device, a fixed vertical post,a frame for carrying a mixing element mounted on the post for free sliding and turning movement, releasable catch means between'the post and frame for automatically holding the latter against down ward movement when raised to its limit of upward movement, and means incorporated with the catch means for allowing of unrestricted turning movement of the frame after the catch means is engaged.

9. In a paint mixer, a vertical post, a frame for carrying a mixing element turnably and slidably mounted on the catch member mounted in connection with the post and extending thereabout in concentric re lation thereto, and a pawl, releasable at will,
